Actually I would not call this a built just
an assyembly of parts/.
Not necessarily a reply to you specifically but its bound to come up. Also that rifle is absolutely beautiful, love the colors of the stock.
It's ridiculous when people say that something is not a build. It can be anywhere between a small simple build to an extremely in depth fully custom build. Its still a build.
When you build a house you buy pre manufactured materials and you put it together, a home builder doesn't require they go cut down a tree and shape it into roof trusses.
When you build a muscle car you buy all the parts and you put them together, you don't necessarily mine the iron, smelt it, and engineer it into parts.
When you build a gaming computer you buy all the parts and assemble them, you don't create semiconductors and create every part needed.
When you build with Lego you have all the pieces and you put the together, you don't melt down plastics into molds and make your own pieces.
When you build a computer program you use an existing code language to make a program, you don't create the language.
People act like building a rifle means creating every part from raw materials. I could see if they said they created a rifle it being false. Building is the action of choosing specific parts and assembling them into something. If you chose the parts and you assembled it, it is a build. Half the work was choosing what you wanted, the other half is putting it together. So yes building a rifle meets the definition and common use of the word "build" on all levels.
If that doesn't count as building then I guess only manufacturers build rifles.
